Finding the world's best luxury car - what's quietest and most comfortable?

Who makes the world's quietest and most comfortable car? Rolls-Royce? Bentley? Somebody else?

We've taken a sample of the world's most luxurious cars from the most prestigious brands to see, whether from front or rear seats, which is the most isolated and comfortable, as well as which is the quietest. The new BMW i7 will tell us whether an electric powertrain moves the game onwards. And we've included a classic Rolls-Royce Silver Cloud to see how far the game as come in the past 60 years.

Join Matt Prior and Matt Saunders for the test.
